The Sky for August 2025

What’s Worth Watching in the Night Sky

The Sky for August 2025

August is a great month for stargazing. Besides the annual Perseid meteor shower, we have some planets gathering in the pre-dawn sky which will make a nice series of photo-ops for early risers. August is also a time when many people vacation to places farther from city lights, giving them the chance to see a really dark sky. Travel during the time near new moon will maximize your dak-sky experience, but even the Full Moon rising over the city skyline can remind us of our connection to the wider universe around us.

The Solar System for August 2025

Mercury is invisible early in the month as it passes near the Sun, but reappears in the morning sky just before sunrise for the second half of August this year. The closest planet to the Sun never rises very high above the horizon before the Sun does, so you will need a clear horizon and good timing to catch it. See calendar entries below.

Venus begins the month rising about 3 a.m. local time, but slowly slips sunward over the course of the month. It passes less than 1 degree from Jupiter on August 12 and is near the Beehive star cluster in Cancer the Crab at the end of the month. See various calendar entries below for details.

Mars is in the constellation Virgo, so low in the west-southwest that you probably won’t see it. It doesn’t slip behind the Sun until January 2026, but right now the angle of its orbit keeps it very low from northern latitudes like Manitoba. (Despite all the hype of supposed “big events” you might have heard about online.)

Jupiter rises in the northeast before 4 a.m. local time at the beginning of the month, and about 2 a.m. by the end of August. It begins to brighter Venus’ lower left, drawing closer and closer each morning until their closest approach on the morning of August 12, 2025. After this, Jupiter rises higher each morning as it moves slowly among the stars of Gemini.

Saturn rises about 11 p.m. at the beginning of August, and by 9 p.m. at month’s end, finally becoming high enough for reasonably-timed observations. Saturn’s rings are tilted almost edge-on to our line of sight, making them difficult to see in a telescope. Neptune is nearby for most of the summer (see below). The waxing gibbous Moon is nearby on the morning of August 12 (see below).

Uranus is in the morning sky a few degrees below the famous Pleaides star cluster (also known as the Seven Sisters). It is too faint to easily see without binoculars, and even a telescope shows it as a faint dot that looks just like the other faint stars. A detailed star-charting app like Stellarium is required to track it down.

Neptune is in the same binocular field of view as Saturn for the entire month, but since it is even farther than Uranus it is invisible without optical aid. Neptune requires good binoculars or a small telescope to even spot, and a large telescope to make it out as anything more than a faint dot. Again, a detailed star chart like those produced by Stellarium is required to tell which tiny “dot” is Neptune.

Of the five known dwarf planets, only (1) Ceres is close enough to be seen in binoculars or a small telescope. In August, Ceres is below and to the left of Saturn and Neptune, wandering among the stars of the constellation Cetus the Whale. You’ll need a chart like the one in the RASC Observer’s Handbook or an app like Stellarium to track it down. Ceres will be easier to spot in the fall as it gets closer and brighter.

Sky Calendar for August 2025

All times are given in the local time for Manitoba: Central Daylight Time (UTC-5). However, most of these events are visible across Canada at the same local time without adjusting for time zones.

Friday, August 1, 2025: First Quarter Moon

The Moon and Antares, 3 Aug 2025Sunday, August 3, 2025: The waxing gibbous Moon is just below the bright red star Antares, very low in the south this evening and into Monday morning.

The Moon and Saturn rise together on the evening of August 11, 2025.Monday, August 11, 2025: A busy night for observers. The waxing gibbous Moon is above and to the right of Saturn as they rise about 10 p.m. CDT. Over the course of the night, the Moon will move closer to Saturn as the pair rise higher and move across the sky. This showcases two of the most important sky cycles: the rising of Saturn and the Moon is caused by the Earth’s rotation every day, while the Moon gets closer to Saturn due to the Moon’s orbital motion around the Earth every month.

Also tonight and into tomorrow, the annual Perseid meteor shower reaches its peak intensity – but this isn’t a great year for it. The nearly-full Moon’s light will overwhelm most of the faint meteors. Best time will be to in the early morning hours of the 12th, in the period from about 2am until dawn. During this period you might see a dozen or two meteors per hour, if you are in a dark sky and watch the sky continuously with no breaks. If you are up this late/early, watch for Venus and Jupiter’s conjunction just before dawn (see below).

Jupiter and Venus conjunction 12 July 2025Tuesday, August 12, 2025 (morning):  The peak of the Perseid meteor shower is offset by the bright Moon, but you can still expect a meteor every minute or two if you’re patient. Jupiter and Venus rises in the north-northeast about 3:20 a.m. local time, less than 1 degree apart and probably tinted orange by any smoke on the atmosphere.

Saturday, August 23, 2025: New Moon

Sunday, August 31, 2025: First Quarter Moon

 

People stare up at the northern lights above them.

Summer Meteor Showers

Outside of the regular events listed above, there are other things we see in the sky that can’t always be predicted in advance.

Aurora borealis, the northern lights, are becoming a more common sight again as the Sun goes through the maximum of its 11-year cycle of activity. Particles from the Sun interact with the Earth’s magnetic field and the high upper atmosphere to create glowing curtains of light around the north (and south) magnetic poles of the planet. Manitoba is well-positioned relative to the north magnetic pole to see these displays often, but they still can’t be forecast very far in advance. A site like Space Weather can provide updates on solar activity and aurora forecasts for the next 48 hours. The best way to see the aurora is to spend a lot of time out under the stars, so that you are there when they occur.,

Random meteors (also known as falling or shooting stars) occur every clear night at the rate of about 5-10 per hour. Most people don’t see them because of light pollution from cities, or because they don’t watch the sky uninterrupted for an hour straight. They happen so quickly that a single glance down at your phone or exposure to light can make you miss one.

Satellites are becoming extremely common sights in the hours after sunset and before dawn. Appearing as a moving star that takes a few minutes to cross the sky, they appear seemingly out of nowhere. These range from the International Space Station and Chinese space station Tianhe, which have people living on them full-time, to remote sensing and spy satellites, to burnt-out rocket parts and dead satellites. These can be predicted in advance (or identified after the fact) using a site like Heavens Above by selecting your location.

Summer Meteor Showers

August is known for the annual Perseid meteor shower, which can often (but not always) produce a nice show for skywatchers. There are also about a dozen minor meteor showers that aren’t worth watching, that AI-driven social media pages are now picking up on and promoting as if they are something to see. Unfortunately, even the best meteor showers barely qualify for the name “shower”, so managing expectations is important.

Even a single meteor arcing across the sky can be a memorable sight, which is probably why many people “wish on a star” when they see one. Meteor observing requires no special equipment and is a casual way to enjoy the sky with the occasional “wow!” moments of a meteor. Don’t hype over numbers, and enjoy your time under the stars, and you will enjoy observing meteor showers.

 

What’s Going On

Meteor showers are basically caused when the Earth passes through a cloud of dust as it orbits the Sun. These interplanetary dust bunnies are left behind by comets or asteroids as they orbit the Sun. When our planet moves through one at high speed, the dust all burns up in our atmosphere, with each grain of sand or tiny rock becoming visible as a meteor (a.k.a. “shooting star”, “falling star”, etc.). Because we can predict their dates in advance, meteor showers are usually one of the first things put onto astronomy calendar websites.

But are meteor showers actually something worth watching? The answer depends on which meteor shower you’re looking at, and how much effort you’re willing to put in to seeing it.

 

The Effects of Light and Time

Most meteors are faint, and so if you have bright lights nearby then you won’t see the faint ones, which cuts your rates down significantly. Observing inside the city means you will see only a quarter or less of the predicted rates. To see a meteor shower well, you need to drive as far from city lights as you can.

If the Moon is in the sky, that’s like city lights you can’t drive away from. When the Moon is in the sky you can also lose about 75% of the meteors predicted.

And if that isn’t enough: meteor rates start very low in the evening, get stronger after midnight, and peak in the few hours before dawn. I have observed the Perseid meteor shower from inside the city before midnight and literally seen not a single meteor per hour. I ahve also observed the Perseids from a rural location with no moon, and seen 2 meteors per minute in the pre-dawn hours (120 per hour). So, these factors make a big difference in what you will see.

A meteor flashes overhead.
Meteor Observing

First, an important point: a typical meteor is only visible for a second or two. Any glance away from the sky during that hour and you might miss one. (Especially if you are glancing at an electronic device, which also ruins your night vision and makes it hard to see anything at night for up to five minutes!) So, to see the maximum number of meteors, you need to watch the sky, uninterrupted, for the whole hour. If you spend 25% of your time looking away from the sky, you will miss 25% of the meteors. To really appreciate the meteor shower, you need to commit to watching the sky without distraction.

Second point: on any given night throughout the year, if you are away from city lights on a dark, moonless night, you can expect to see between 1 and 10 meteors per hour. That’s the background rate in between meteor showers, the random dust in between the dust bunnies that is spread out across the solar system.

So, any meteor “shower” that lists a rate of less than 10 meteors per hour basically is no different than any other night. (OK, it *is* different scientifically, but for the average skywatcher you won’t even notice it.) This is why I’ve never promoted the dates of the Alpgha Capricornid meteor shower, which peaks on July 31 with a maximum theoretical rate of 3 meteors per hour. But I’m seeing social media posts announcing that it is on now and combining with the Perseids in a “rare” “double” “shower” “event” – and every one of those words is misused in this case. It happens every year, there are actually about 8 meteor showers active right now, and if you didn’t notice it last year it won’t be a big deal this year either. Complete hype, no substance.

So What Is Worth Watching?

In the summer, the answer is easy: the Perseids. That’s it. All the other minor meteor showers are underwhelming for the average skywatcher. The South Delta Aquariids, which peak on July 31, have a rate of between 5 and 10 meteors per hour, so if you are a hardcore meteor observer that’s one to try as well when (like this year) it lines up with the dark of the Moon.

In 2025, the Perseids peak when the Moon is nearly full, so even if you go out in the pre-dawn hours of August 11-12 (the peak night) you will likely only see 10-30 meteors per hour this year. For numbers, it’s not a great year because of the Moon. But, that means there’s no real need to drive far from the city; any reasonably dark space where you can see the sky will do this year.

 

It’s Not All About Numbers

Remember, though: the sheer number of meteors isn’t the only metric to use. I have seen single meteors that were so bright and beautiful they have stuck in my memory for decades. Often, evening meteors tend to be long and bright – so even if there aren’t a lot, the ones you see can be well worth it.

The bottom line is: meteor showers are a good time to see shooting stars, but don’t expect a laser light show. Each streak of light you see is a piece of dust left over from the formation of the solar system, a reminder of the era when planetary collisions were common as they shaped our planet. Keep expectations low, and appreciate whatever meteors you do manage to catch. A night under the stars is always time well spent.

The Sky for April 2025

“April showers bring May flowers”, goes the saying, and it’s true that April does often have a lot of rain (or at least clouds) for Manitoba. On clear nights, though, we get a unique view away from our Milky Way galaxy and out into the darkness of intergalactic space. With fewer bright stars to guide you, contemplate the darkness between the stars: that’s what most of the universe is like.

The Solar System

Mercury is technically in the morning sky in April, but the angles dictate that it stays very low to the horizon (and probably invisible) from Manitoba. Southern hemisphere viewers get their best morning views this year of the elusive innermost planet.

Venus has moved between us and the Sun (well, just above the Sun) and is now low in the east before dawn.

Mars is still bright in the evening sky, forming an ever-changing triangle with the bright stars Castor and Pollux in Gemini.

Jupiter still shines brightly in the evening sky, high in the southwest after sunset in the constellations of Taurus.

Saturn has moved into the morning sky, but like Mercury it is very low to the horizon and probably invisible from Manitoba until near the end of the month. Saturn will be a summer feature this year, so wait a few months and you’ll get a great view.

Uranus sets very soon after the sun and is not easily observable this month. You’d need at least binoculars, and probably a small telescope, to be able to spot it, and even then it’s so far from Earth that it appears as just a faint “star” in a field of other stars.

Neptune is invisible without a telescope at the best of times, and this month is not the best of times. Neptune is near Venus in the bright twilight sky before sunrise and is unobservable this month.

Of the five known dwarf planets, none are visible with typical backyard telescopes this month.

Sky Calendar for April 2025

All times are given in the local time for Manitoba: Central Daylight Time (UTC-5). However, most of these events are visible across Canada at the same local time without adjusting for time zones.

Tuesday, Apr. 1, 2025 (evening): The thin crescent Moon is above the Pleiades star cluster in the evening sky. Both with fit comfortably into the field of view of typical household binoculars.

Wednesday, Apr. 2, 2025 (evening): The thin crescent Moon stands above and to the right of Jupiter in the west after sunset. in the evening sky. You should be able to see both in binoculars at the same time. Look for some tiny dots in a line very close to Jupiter – those are some of its largest moons! Callisto is the one farthest to the right and likely the one most easily seen in binoculars. Good eyesight or higher magnification may show a second dot closer to the bright planet – that’s Ganymede and Europa, which appear right beside each other tonight, merged into a single point.

Thursday, Apr. 3, 2025 (evening): The waxing crescent Moon is about halfway between bright white Jupiter (to its lower right) and reddish Mars (higher and to its left) in the west and southwest after sunset.

Friday, Apr. 4, 2025 (evening): The first-quarter Moon forms an almost-triangle with Mars and the stars Castor and Pollux. From bottom left, we have Mars, Pollux, and Castor.

Saturday, Apr. 5, 2025 (evening): The waxing gibbous Moon is to the left of Mars tonight. Both fit into the field of view of typical binoculars. This is a good chance to compare the reddish colour of Mars with the grey-white tones of the Moon.

Thursday, Apr. 10, 2025 (evening): After weeks of flirting as a triangle, Mars forms an almost-straight line with Castor and Pollux this evening. Nothing significant about this, other than it looks cool from our point of view here on Earth. (Mars is only 185 million kilometers away, while Pollux is 324 billion km and the six stars of the Castor system are 25 trillion km distant. Their apparent alignment is in in two dimensions as seen from this particular corner of the universe.)

Saturday, Apr. 12, 2025: Full Moon

Sunday, Apr. 20, 2025: Last Quarter Moon

Monday, Apr. 21, 2025 (evening): Tonight is the peak of the annual Lyrids meteor shower. Beginning around 11 p.m. local time you can expect to see a dozen or so meteors per hour from a dark sky location. The show intensifies after midnight and into the pre-dawn hours of the 22nd. As meteor showers go, this one isn’t at the same level as the Geminids of December or even the Perseids of August, but it’s a nice evening under the stars in cool spring skies before the mosquitoes hatch.

Thursday, Apr. 24, 2025 (morning): The thin crescent moon is visible off to the right of bright Venus in the eastern sky about a half-hour before sunrise.

Friday, Apr. 25, 2025 (morning): The thin crescent Moon has moved to the lower left of Venus. Both are visible in the eastern sky just before dawn.

Sunday, Apr. 27, 2025: New Moon

Tuesday, Apr. 29, 2025 (evening): The crescent Moon reprises its appearance with Jupiter, although this time they are too far apart to fit into the view through binoculars at the same time. The Moon is slightly below and to Jupiter’s right this evening after sunset.

Also tonight, Mars begins its approach to the Beehive star cluster (also known as Messier 44 or M44) in the constellation of Cancer the Crab. While the cluster is just a faint smudge in binoculars, a small telescope shows a few dozen stars. Mars will skirt the northern edge of the cluster during the first week or May, making for interesting pictures for small telescope users.

Wednesday, Apr. 30, 2025 (morning): You might be able to glimpse Saturn through binoculars starting today if you’re up early. Start looking about 5:30 am local time. First, find Venus, which is the brightest (and probably only) “star” you will see in the bright twilight glow in the east. Put Venus near the “10 o’clock” position in your binoculars, and then look for a really faint object near the “4 o’clock” position. That’s Saturn. It will likely only be visible for a short window between when it rises and when the sky is too bright to see it/

Wednesday, Apr. 30, 2025 (evening): The crescent Moon stands above Jupiter in the western sky after sunset.

People stare up at the northern lights above them.

Outside of the regular events listed above, there are other things we see in the sky that can’t always be predicted in advance.

Aurora borealis, the northern lights, are becoming a more common sight again as the Sun goes through the maximum of its 11-year cycle of activity.

The Sky for December 2024

Winter nights start early and last long, making them perfect for star watching. Except for the temperature… and the clouds… Catch a clear December night, though, and you’ll be treated to the brightest stars and planets in the sky.

Comet Updates

The great fall comet, 2023 A3 (Tsuchinshen-ATLAS) has come and (mostly) gone, providing some beautiful views in October and November. It’s still in the evening sky, but only visible with telescopes as it rockets away from the inner solar system.

Another comet, Comet 2024 G3 (ATLAS), was discovered by the same program that helped find 2023A3 – the Asteroid Terrestrial-impact Last Alert System, or ATLAS. This comet, a so-called “sun-grazer” will likely get quite bright, but only be visible in the daytime sky and from the southern hemisphere, so that means most Manitobans won’t be able to see it.

The Solar System

Mercury passes between Earth and Sun (and slightly above the Sun as viewed from Earth), so it remains invisible until the second half of December, when it appears low in the southeastern sky just before sunrise. On the morning of December 28, the thin crescent Moon is nearby, next to the reddish star Antares.

Venus spends the month in the evening sky, low in the southwest after sunset. The thin crescent Moon approaches on the 3rd, is nearby on the 4th, and is still close on the 5th, making a nice photo op. It stands a little higher at sunset each night, and sets about three hours after sunset. In a telescope, Venus displays phases like the Moon, and in December it is about 50% illuminated, a tiny half-moon shape at high power.

Mars rises in the northeast about 9pm in early December, and a bit after 7pm by month’s end. By midnight it is high in the south, providing the clearest telescope views. Mars reaches its best next month, its closest point to Earth on this orbit, but it’s worth looking at now.

December 2024 belongs to Jupiter, The giant planet reaches opposition on December 7, 2024, rising at sunset, hitting its highest altitude in the south around local midnight, and not setting until sunrise. Jupiter dominates the evening sky, outshining everything else except Venus and the Moon. A small telescope will reveal some of Jupiter’s banded clouds, while its four largest moons are visible in binoculars as tiny “stars” in a line on either side of the planet.

Saturn is low in the south at sunset, and sets before midnight. The rings are nearly edge-on as seen from Earth, but visible in a telescope with more than about 30x magnification. Saturn edges closer to Venus and the setting sun each night, making it lower and harder to get clear telescopic views.

Sky Calendar for December 2024

Dec. 1 : New Moon

Dec. 4: The thin crescent Moon is below Venus, just after sunset, low in the southwestern sky.

Dec. 5: The thin crescent Moon is to the left of Venus in the southwestern sky, just after sunset.

Dec. 7:  Jupiter at opposition, visible all night.

Dec. 7: The crescent Moon is below and to the right of Saturn in the evening sky.

Dec. 8: The First Quarter Moon is to the left of Saturn in the evening sky.

Dec. 13-14: Peak of the Geminid meteor shower. The nearyl-full Moon will reduce the number of meteors seen, but you can still expect 20-40 meteors per hour in late evening and early morning.

Dec. 14: The nearly-full Moon forms a line with Jupiter and the bright star Aldebaran in the eastern sky.

Dec. 15: Full Moon

Dec. 17: The waning gibbous Moon is just above Mars as the pair rises in the East about 7:15 p.m. local time.

Dec. 21: The winter solstice occurs at 4:20 a.m. Central Time, marking the beginning of astronomical winter in the northern hemisphere (and the beginning of summer in the southern hemisphere).

Dec. 22: Last Quarter Moon

Dec. 22-23: The peak of the Ursids meteor shower, which radiate from near the North Star. They only produce a few meteors per hour, though.

The Sky for August 2024

August brings the return of some planets to the evening sky, the most famous meteor shower of the year, and longer nights than we’ve seen for a couple of months. The Milky Way is on full display, offering an unforgettable view from a dark, moonless sky. Unfortunately all of these benefits will likely be offset by smoke in the air from forest fires across Canada, which has become a fixture of summertime observing for the last several years.

The Perseid Meteor Shower

The annual Perseid meteor shower is the most famous meteor shower of the year, although it is not the best one of the year. Its occurrence in August during summer vacation likely makes it more accessible than the much better Geminids, which occur in mid-December. For a complete rundown on the Perseid meteor shower, check out this blog post.

2024 is a good year for the Perseids, since the peak time occurs with the Moon out of the sky. The thing about meteor showers is, they peak in the few hours before dawn for any given location. So to see the Perseids at their best, you want to observe from about 1:30 a.m. to dawn. There will be almost no meteors before midnight – you might see one or two, and the ones you do see will likely be bright ones, but it won’t be much of a “shower” unless you stay up all night.

To observe the Perseids, get away from city lights. Light pollution will wash out the fainter meteors, and there are a lot more faint meteors than bright ones. Bring a reclining lawn chair and blanket to ward off the early-morning chill, and set up facing the darkest part of the sky (or straight up, if you’re in a nice dark spot). Turn off your electronic devices and your car’s lights – any stray light will make it hard to see the meteors for you and anyone near you. The meteors only last a second or two, so you need to watch the sky continuously – literally, don’t blink or you’ll miss it.

You can also try and take pictures of meteors – set up your camera on a tripod and take a bunch of time exposures of the sky. If you’re lucky, a meteor will happen while you’re taking a picture.

We’d love to show your Perseid pics on Dome@Home, our online astronomy show. Send them to space@manitobamuseum.ca and then tune in to our August 28th show at 7 p.m. Central on the Museum’s Facebook and YouTube channels.

The Solar System

Finally, some planets are visible in the evening sky! Barely…

Mercury is still on the evening side of the sky, but in August it sets just after the Sun and so isn’t visible for Canadian viewers. Folks farther south still have have a chance to catch it early in the month, low in the west just after sunset.

Venus has appeared in the evening sky, although like Mercury it is still low in the sky; only its great brightness allows it to be spotted very low soon after sunset. The thin crescent moon is nearby on August 5th.

Mars rises about 2 a.m. local time in the northeast, inconspicuous compared to nearby Jupiter and both the Pleaides and Hyades star clusters. Mars and Jupiter pass less than half a degree apart on the morning of August 14th; see the Sky Calendar entry below for details.

A simulated view of Saturn and its rings.

Jupiter is the brightest “star” in the eastern sky after midnight, outshining all the visible stars as it cruises through the stars of Taurus. The waning crescent Moon is nearby on the morning of August 27.

Saturn rises about 11 p.m. local time early in the month, and moves into the south by dawn. The ringed planet reaches opposition on September 8, so it’s coming into its best viewing position for the year. The rings are only tilted about 4 degrees to our line of sight, making them appear very thin from our point of view. The nearly-full Moon is to Saturn’s left on the evening of the 21st.

Sky Calendar for August 2024

Aug 4: New Moon

Aug 11 – Aug 12 (morning sky): Best viewing for the annual Perseids meteor shower; see featured article above. Decent rates should occur the morning before and after as well.

Aug 12 (evening sky): First Quarter Moon

Aug 14 (morning sky): Jupiter and Mars are close together in the morning sky, separated by less than the size of the Full Moon. They’re still pretty close the morning before and after this date.

Aug 19: Full Moon

Aug 20-21 (after midnight into morning sky): The waxing gibbous Moon is to the left of and slightly above Saturn. The two are only about 3 degrees (6 Full Moon diameters) apart, fitting easily into the same binocular field-of-view.

Aug 26: Last Quarter Moon

Aug 27 (morning sky): The waning crescent Moon is above Jupiter, rising together in the morning sky about 1 a.m. local time in the morning sky. Mars is below and to the left, forming a not-quite-right triangle. The red supergiant star Aldebaran is to Jupiter’s right along with the Hyades star cluster, with the Pleaides above them all. The morning rising of these star clusters remind us that winter is coming.

Aug 28 (morning sky): The Moon, Mars, and Jupiter form a very squashed triangle pointing downwards in the eastern sky before dawn.

Aug: 29 (morning sky): By this morning the Moon has moved farther on, still forming a rough line with Mars and Jupiter in the early morning sky.

Meteor Showers in Summer (2024 Edition)

Meteors

A meteor (a.k.a. falling star, shooting star) looks like a bright streak across the starry sky that lasts for a second or two before fading away. Most people believe they are rare enough that you should make a wish when you see one, but they are surprisingly common if you watch the sky a lot. On any given night with no Moon, if you get away from city lights and watch the sky continuously, you’ll see up to a half-dozen meteors per hour. Any light sources – the Moon, city lights, you phone – will reduce that number to near zero.

Each meteor you see is actually a tiny piece of dust about the size of a grain of sand which is burning up in the Earth’s atmosphere. Space isn’t empty, you see – it’s dusty, with all the dust leftover from the big construction job that was the formation of the solar system. As the Earth orbit the Sun, it plows through the dust at over 100,000 kilometers per hour. It’s a one-sided collision, and the poor speck of dust disintegrates in a flash of light that we can see from the ground as a meteor.

Meteor Showers

So far, so good – you can see these little specks of dust as they vaporize, and they pretty much occur randomly all the time, we just don’t usually notice. But, it turns out that space isn’t evenly dusty. There are spots, just like in your house, that have more dust than others. In my house, these dust bunnies congregate under the furniture and anyplace the air vents push them; in the solar system these dust bunnies remain where they were shed, in the orbital paths of comets. The solar system is crisscrossed by trails of dust left behind by various comets (and a few asteroids). If the Earth’s orbit intersects one of those trails, we will fly through an interplanetary dust bunny every year around the same time. That’s a meteor shower.

The name “meteor shower” makes you think you can see a lot more meteors than on other nights. But here’s the thing: “a lot” can mean different things. Forty times the normal rate sounds like a lot, until you remember it’s forty times about one meteor per hour. There are over a hundred meteor showers catalogued, but there are only a couple of meteor showers a year that produce more than forty meteors an hour. Even during an official meteor “shower”, you can probably only expect to see a half-dozen meteors per hour, and that’s under perfect skies with your eyes watching the sky 100% of the time.

The Perseids for 2024

So, most meteor showers don’t produce many meteors; that’s the bad news. The good news is, the Perseids in August is one of them, which makes them probably the most famous meteor shower of all. And, in 2024 the Moon will be out of the sky during the crucial morning hours. If you can get away from city lights under a clear, dark sky, you might see up to 60 meteors an hour – one a minute – in the early morning hours of August 12.

That’s pretty specific timing, but luckily the Perseids “dust bunny” is more than one day wide. The Earth actually enters the outer edge of it in late July, and each morning the rates will increase until the peak on the 11th-12th. So, we have several chances to see a decent Perseids display this year.

The key point to remember is that all meteor showers are best between about 1:30 a.m. and 5 a.m. local time. Pre-midnight observing might be 1/10 or less of the morning rates. Really, you have to stay up all night to see this.

To get the best view, get as far away from city lights as practical, and set up a reclining lawn chair or blanket so you can lean back and see as much of the sky as possible. Keep all the lights around you off, especially if you are in a park of other spot with other observers. One peek at your phone will shut off the natural night vision of your eyes for up to ten minutes, so you really need to avoid looking at any lights. (If you need to keep your car running, cover the headlights with a blanket or something so you don’t blast the whole park with your lights!) If you have any lights nearby, put them behind you out of your view, and just watch the sky. You don’t need a telescope or binoculars – in fact, those instruments restrict your field of view so much that you probably won’t see any meteors through them at all. The meteors can appear anywhere in the sky, and they only last a second or two – literally, don’t blink or you can miss them.

Meteors and Cameras

You can take pictures of meteors, but it involves a little luck, and some understanding of your camera. If you have a DSLR or mirrorless camera, you can put it on a tripod and set your exposure manually for something like 5 or 10 seconds – you’ll get a lot of pictures of stars, but if you’re lucky a meteor will happen while you’re shooting, and it will show up in one picture.

If you’re using your phone camera, you might need to download a better camera app than the one your phone came with – check out the app store for one that is designed for night or sky photography. The same tactic applies – take lots of pictures, and hope you catch one. Make sure the light from your camera doesn’t interfere with your vision, though – just take the pictures now, and look at them later.

One thing to watch for: satellites. There are piles of satellites that will show up in your images as streaks of light. You can tell satellites by the trail being the same brightness and thickness throughout; meteors tend to start faint and narrow, get brighter and wider, and then trail out again.

Other Summer Meteor Showers

While technically there are other meteor showers in July and August, in practice these are not noticeable to the average observer and are scientific designations only. They’re named after the constellation or star that the meteors appear to radiate from, but most of them produce a meteor every couple of hours or so – not even a spritzing, let alone a shower. Even the bigger South Delta Aquariid meteor shower, which peaks in late July, only produces about 5 meteors an hour at best. If you are interested in these minor meteor showers, there is backyard science that can be done by tracking them with a camera, though; visit the International Meteor Organization for some great information on getting deeper into the science of meteor observing.

tl;dr: The morning of August 12th between 1:30 a.m. and 4:30 a.m. you will probably see quite a few meteors. The morning before and after, you’ll still see a good number. The rest of the summer, you’ll hardly see any, but you might see one anytime you are looking at the stars.
